I don’t find Alan Rusbridger to be a good comparison: he was taking lessons weekly from some of the best pianists in the world, sometimes for multiple hours per week, only worked on this one piece and it took him two years to be able to perform it for friends. If I remember correctly, he started this project as a pianist who played in ensembles at piano camp. It’s been a few years since I read the book.
You have already defined what you are willing to do, how much time you are willing to spend, and that you are only willing to dabble in music at random. Will you progress to playing etudes in 10 years? No one can guarantee you that but how can that matter? If you were told ‘probably not’, would you change? You have already decided what you are WILLING to do and are even asking what else you can skip. Keep doing what you are willing to do and see what happens. None of us should want relatively high level goals in anything but not being willing to make a relatively high level commitment to get there. There are many unanswered elements: is your 30 min per day practice meaningful and focused or wandering? Do you choose music based on your goals or is it totally by whim? Is anything done to improve technique? You should be seeing progress with what you are doing now if that plan will not change. These are questions you should ask yourself, including whether you are willing to adapt if what you are doing is not working
I also don't feel comfortable forcing myself to play according to Grade books, I just prefer to find songs that seem relatively doable online and just choose randomly (at the moment I'm handpicking certain Chopin nocturnes). I just lose interest and just give up when I force myself to do the songs on my grade books in a progressive manner. Will this severely hamper my progress?
My aim is to eventually be able to play the CHopin Etudes or some of Rachmaninoff's works in 10 years' time. ..... I dont aim to play perfectly, but rather to play at a modest level..... I'm aiming for a modest goal of just being your average 'mediocre' amateur pianist who will miss some notes here and there...

I am a firm believer that you don't really make "backsliding" progress when you learn something.
Tell that to Pogorelich.
Just play and practice when you feel like it.
That takes willpower and that never works.Set a time schedule and make your practice a habit, and you'll do it without all the angst.Read these two books:Atomic Habits by James ClearThe Power of Habit by Charles Duhigg. Available at your local library, on Overdrive or Hoopla, etc.
And btw, although pop science books can be useful, they are far from authoritative. People tend to read too much into them.
I agree and rarely recommend a pop science book, but the advice in these was generally not too bad, and in line from what I remember from grad school. I do know that piano students who intend to fit practice into spare moments instead of having a plan rarely ever find the time.
Apparently only 7% of gym members know their gym was closed for COVID this year.
